Paper 3 is secured within the binder and to section I by rings mountedon section I passing through marginal holes provided in the paper. Therings are arranged in parallel order and each comprises two separableposts 4 extending upwardly and curving to meet at the top. The lower endof each post 4 is welded or secured to corresponding parallel strips 5and 6 disposed flat against the inner side of section I and adaptedselectively to be placed edge to edge to close the posts or rings 4 atthe top or relatively separated to open the rings. Strips 5 and B areconnected by two sets of spaced parallel links I which maintain thestrips in parallel alignment.

Each of the pairs of links i is disposed above and below strips 5 and 6and pivotally connected thereto by pins 8. Each pair of links is securedto section I by a pivot post 8 extending vertically I the 4 section Iand 'Recesses I 0 along the adjacent edges of the strips bindeni t be ci e between strips 5 and 6.

The base to which the bindei istojbesecured is itself secured yifithihthe brief case willbe described. "The base comprises} flat se niflexibleboard 2| having afabric coverifigf22.

Two-edgesof the fabric, covering'fl are extended along-.one' sideoftheboard 2lf inthefornijof a is within the case it provide ahingedconnection. The flap 23 should be sewn near and along one edge I! of thecenter section for pivotal movement of the base along an axissubstantially close and parallel thereto.

Two round posts 24 project upwardly from the base and are spaced toregister with two cor-- responding holes 25 in the center section I ofthe binder along the longitudinal center line thereof. An annular recess26 having a vertical width corresponding to the approximate thickness ofstrips 5 and 6 is out near the top end of each post. Recesses 21corresponding to the smaller diameter of posts 24 within recesses 26 areprovided in the adjacent edges of strips 5 and Ii to register with holes25.

Thenbinder is secured to the base and within the case by placing thesame on thebase with strips 5 and 6 spaced apart and with posts 24projecting through holes 25 and between the strips. The binder is thenlocked to the base by closing the strips to engage the recesses 26 ofposts 25.

By opening locking device II and separating the strips 5 and 6 the ringsare opened and the binder is also released from its base so thatindividual sheets of paper maybe replaced in the hinder or the entirebinder replaced on its base. Closing of the binder locks the same to thebase.

The invention provides a simple effective manner of securing the binderto the base operable by the same mechanism as the binder itself. Theinvention is adaptable to a wide variety of uses other than thatdescribed including applications where the binder is to be fastened to apermanent fixture or holder.

Various embodiments of the invention may be carried out within the scopeof the accompanying claims.

I claim:

1. A loose-leaf binder and a base therefor comprising a center ringsection for said binder having a pair of laterally separable platesdisposed in a horizontal plane edge to edge with correspondingupstanding ring posts disposed to co operate in securing leaves in thebinder, said plates having complementary recesses in their meeting edgesconstituting at least two holes upwardly therebetween, posts extendingupright from said base and spaced to register with said holes, andinterlocking means operable by the closing together of said laterallyseparable plates to secure said last named posts within said holes tosecure said binder to said base.

2. In a ring post loose-leaf binder having-two separable ring postmounting strips with up standing corresponding ring posts thereon, linkspivoted to and joining the strips in a common plane to limit theseparation thereof, and means for securing the binder to a basecomprising at least one upstanding post secured to said base andextending upwardly between said strips, fastening means to receive saidlast named post between said strips and provide for interlockingengagement of the same by the strips upon closure of the latter and ofsaid ring posts together to secure said binder upon said base, and alatch disposed to lock said strips together when .closed upon saidupstanding posts.

3. In a loose-leaf binder having a center section, ring post mountingstrips disposed edge to edge, connecting means pivoted centrally to saidcenter section and pivoted at the opposite ends thereof to thecorresponding strips to provide for lateral movement of the stripstoward and away fromeach other, and rings for securing the leaves withinthe binder comprised of two meeting parts seemed, to said correspondingmounting strips,

said'strips being adapted to open and close said rings uponcorresponding separation and closing of the strips together, means forsecuring said binder upon a base comprising posts extending upright fromthe base and adapted to register with and extend through correspondingholes in the center section of said binder in alignment with the meetingline of said strips, notches in the meeting edges of said strips toregister with said holes, and annular recesses at the upper end of saidposts whereby the recesses of said posts are adapted to be engaged bythe notches in said strips in the closed position and released when inthe open position selectively to secure and release said binder uponsaid base.

4. In a loose-leaf binde having a center section, ring posts mountingstrips disposed edge to edge, connecting means pivoted centrally to saidcenter section and pivoted at the opposite ends thereof to thecorresponding strips to provide for lateral movement of the stripstoward and away from each other, and rings for securing the leaveswithin the binder comprised of two meeting parts secured to saidcorresponding mounting strips,

said strips being adapted to open and close said rings uponcorresponding separation and closing of the strips together, means forsecuring said binder upon a base comprising posts extending upright fromthe base and adapted to register with and extend through correspondingholes in the center section of said binder in alignment with the meetingline of said strips, notches in the meeting edges of said strips toregister with said holes, annular recesses at the upper end of saidposts whereby the recesses of said posts are adapted to be engaged bythe notches in said strips in the closed position and released when inthe open position selectively to secure and re- V the binder to saidbase.
